Set-up, function, section
Set-up
▶ The IAC-P valve basically consists of:
▶ Housing (1) with connection surface
▶ Control spool (2) with compression spring (3)
▶ Solenoid and pole tube (4) with central thread
▶ Position transducer (5)
▶ Pressure sensor (6)
▶ Integrated IAC-P digital control electronics (7) with
bus connection (X2) and central connector (X1).
Functional description
▶ If solenoids (4) are not operated, spool position A → T
(with type STW 0196-1X/1 additionally B → T)
▶ Functions:
– Flow control (Q)
– Pressure control (p)
– Override control p/Q
▶ The command value can be defined either via an analog
interface (X1) or via the field bus interface (X2, X3).
▶ The actual value signals are provided via an analog
interface (X1) and may be read additionally via the field
bus (X2, X3).
▶ The controller parameters are set via the field
bus (X2, X3).
▶ Separate supply voltage for bus/controller and power
part (output stage) for safety reasons
Type STW0195-2X/…
The digital integrated control electronics enables the
following fault detection (diagnostics):
▶ Cable break of pressure sensor supply line (6)
▶ Undervoltage
▶ Cable break position transducer (5)
▶ Communication error
▶ Watchdog
▶ Cable break of command value inputs
The following additional functions are available:
▶ Pressure ramp
▶ Internal command value profile
▶ Release function analog/digital
▶ Error output 24 V.
WINPED PC program
To implement the project planning task and to parameter-
ize the IAC-P valves, the user may use the WINPED com-
missioning software (see accessories).
▶ Parameterization
▶ Diagnostics
▶ Comfortable data administration on a PC
▶ PC operating systems: Windows 2000 or Windows XP

Notice:
Due to the design principle, internal leakage is inherent to the
valves, which may increase over the life cycle.
The tank line must not be allowed to run empty. If required by
the installation conditions, use a suitable preload valve.
Notice:
The PG fitting (8) must not be opened. Mechanical adjustment
of the adjustment nut located below is prohibited and damages
the valve!

als
Standards Data sheet
Mineral oils HL, HLP, HLPD, HVLP, HVLPD NBR, FKM DIN 51524 90220
Bio-degradable ▶ Insoluble in water HETG NBR, FKM ISO15380 90221

Important information on hydraulic fluids:
▶ For more information and data about the use of other hydraulic
fluids, refer to data sheets above or contact us!
▶ There may be limitations regarding the technical valve data
(temperature, pressure range, life cycle, maintenance intervals,
etc.)!
▶ The flash point of the hydraulic fluid used must be 40 K higher
than the maximum solenoid surface temperature.
▶ Flame-resistant – containing water:
– Maximum pressure differential per control edge 50 bar
– Pressure pre-loading at the tank port > 20% of the pressure
differential, otherwise increased cavitation
– Life cycle as compared to operation with mineral oil HL, HLP
50 to 100%
▶ Bio-degradable and flame-resistant: When using these hydraulic
fluids that are simultaneously zinc-solving, zinc may accumulate
(700mg zinc per pole tube).
3)
The cleanliness classes specified for the components must be
adhered to in hydraulic systems. Effective filtration prevents
faults and at the same time increases the life cycle of the com-
ponents.

wear and aging.
Project planning and maintenance instructions
▶ Connect the valve to the supply voltage only when this
is required for the functional processes of the machine.
▶ Do not use electrical signals provided via control elec-
tronics (e.g. “No error” signal) for switching safety-rele-
vant machine functions (see also EN ISO 13849 “Safety
of machinery – safety-related parts of control systems”).
▶ If electro-magnetic interference must be expected, take
appropriate measures to ensure the function (depend-
ing on the application, e.g. shielding, filtration).
▶ The devices have been tested in the plant and are sup-
plied with default settings.
▶ Only complete units can be repaired. Repaired devices
are returned with default settings. User-specific settings
are not maintained. The machine end-user will have to
retransfer the corresponding user parameters.
